Objective To study effect of the components in serum of Banxia Xiexin Prescription and different herbal formula on the apoptosis of cell BGC-823 and apoptosis-related gene expression. Methods The genic expression of bcl-2 and bax was tested by S-P immunohistochemistry technique. Results The apoptotic index of the groups of Xinku in Banxia Xiexin Prescription was significantly higer than that in the groups of Xingan, Kugan, Ganbu and the intact prescription (P

Objective:To prepare anti-human PSA(Prostate Specific Antigen)monoclonal antibodys(McAb)and identify their distinct biological function.Methods:Prostate Specific Antigen(PSA)was purified by salting out,ion exchange and gel filtration method from human sperm.The purity and contents of the objective protein was detected by SPS-PAGE and f-PSA EiAsy.BALB/c mice were immunized with the purified PSA purified.Then the immunized splenocytes were isolated and fused with a hypoxanthine-aminopterin-thymidine-sensitive mouse myeloma cell line SP2/0.Positive clones were screened by limiting dilution method.After acquisition of the hybidomas secreting anti-PSA monoclonal antibody,investigation of their sub-class isotype,binding affinity and specificity were followed.Results:Fifteen hybridoma cell lines that could continuously secret anti-PSA monoclonal antibody were obtained.An Ig subclass was classified as IgG2a and the other were IgG1.Conclusion:This McAb is propitious to establish PSA-ELISA diagnose reagent.
